WebMar 27, 2024 · Explanation: 22 7 and π are not equal, but we can say that. π ≈ 22 7 they are approximately equal. π is an irrational number - it is an infinite, non-recurring decimal. Its … The purpose of the proof is not primarily to convince its readers that 22 / 7 (or 3 + 1 / 7) is indeed bigger than π; systematic methods of computing the value of π exist. If one knows that π is approximately 3.14159, then it trivially follows that π < 22 / 7, which is approximately 3.142857. See more Proofs of the mathematical result that the rational number 22/7 is greater than π (pi) date back to antiquity. One of these proofs, more recently developed but requiring only elementary techniques from calculus, has … See more That the integral is positive follows from the fact that the integrand is non-negative; the denominator is positive and the numerator is a product of … See more In Dalzell (1944), it is pointed out that if 1 is substituted for x in the denominator, one gets a lower bound on the integral, and if 0 is substituted for x … See more The above ideas can be generalized to get better approximations of π; see also Backhouse (1995) and Lucas (2005) (in both references, however, no calculations are given). For … See more 22/7 is a widely used Diophantine approximation of π. It is a convergent in the simple continued fraction expansion of π. It is greater than π, as can be readily seen in the See more The proof can be expressed very succinctly: $${\displaystyle 0<\int _{0}^{1}{\frac {x^{4}\left(1-x\right)^{4}}{1+x^{2}}}\,dx={\frac {22}{7}}-\pi .}$$ Therefore, 22/7 > π.
